Hi guys,

im planning to take the "t61" to a turbo shop to have the balance checked as we don't know how precise their computer balance is, it may be "good enough"

If anyone has ANY speculation on failure this turbo may incur / what i should ask the turbo re-builder please put it forward now :)

i think the best answer we will have on the life of the turbo will come from a turbo specialist because otherwise you'll have to wait till it fails/ if it fails....

tracking my turbo its still in USA but ill get a USPS notification that my item has been loaded onto a plane a day after i've actually received it :p

UPDATE:
spoke to the turbo guy, he had some nasty words to say about "china" turbo's
he said the shafts they use are not good quality and either are the wheels, hes going to charge $200aud to pull it apart, check everything including the balance and re-assemble it

Depending on what your oil pressure is, you might want to use that restrictor.

In the Honda word it is usually necessary to run a restrictor even on a journal bearing turbo or usually oil is pushed past the seal and leaks into the exhaust housing during boosting.

You'll probably be fine without it if you have stock oil pressures.

i've picked up a cheap 57trim ct26 as well, (too good price to pass up) so if the turbo turns out to be rubbish at least i've got a back up plan.

seems pretty pricey BUT think about the cost of a new engine.......certainly worth $200 IMO

What i was gonna say too..Why would a engine fail just because the turbo does ?

If the compressor wheel explodes, it'll be sucked into the engine, and nothing good will come of that

Can pretty well throw the IC in the Bin if a Comp wheel lets go, I WOULDN'T trust a fresh rebuilt engine to survive no matter how well it's been cleaned out, all it takes is for one piece of wheel to dislodge and get sucked in to end it all.

Would be very interesting to see how a piece of compressor wheel make it all the way through the IC pipe and intercooler through all of the turns and bends and into the motor. I think it would trash the first half of the IC track and stick in the inter-cooler. Anyway it goes down is not good for anyone, but vids are nice if it does happen.

When they explode they break into very small fragments.....

"Aluminium oxide" oxide ring any bells?

The particles are very abrasive as I siad I wouldn't be trusting a fresh engine to an IC that's had a Turbo let go, you can do as you please.

Thank you for catching my point. When a turbo builder says how bad the quality of the shaft and compressor wheel is that can lead to very bad things. I don't dout the quality of the rest of the components but if they cheap out on a part that rotates at 100+K rpms and it explodes, it won't be left in a couple large pieces that will simply rest at the lowest part of the IC system. It will potentially go through everything destroying some rather costly components along the way.

edit: Honestly this turbo may even be worth it to purchase and have it rebuilt with a new wheel that would fit from garrett or a proven company. I'd still be considerably cheaper then any boss series of comparable specs

edit edit:in my mind the BEST case scenario for all of us who are interested would be to get one to MDC. I don't know if he still has the tools to break it down and do a thorough check and balance of the turbo, but i can say i'd take his word about this turbo over any one elses.

when my ct26 let go 3 small shards of the compressor wheel snapped off after hitting the housing. i found all 3 in the side tank of the intercooler, luckily due to the design there was a ledge for them to get caught on..

I drove the car home gently maybe 500m and they made their way through 2m of intercooler piping.. should have towed it in hindsight, guess i got lucky.

was speaking to my turbo builder,

judging from the pics all the components are balanced before assembly(see how the exhaust wheel has been balanced but not the end of the shaft?)

does not look to be balanced post assembly, which means they'res more potential for the balance to be off.

based on what he says post inspection i think ill be taking the housings and buying a new core to fit (garret) and have the housings machined to fit. could work out the same price as a genuine garret and have the same internals but will be bolt on.. ill wait till it arrives then report.
